    General Description
    Solitary monoecious hapaxanthic tree palm; stems 6-16 m tall, ca. 20-40 cm diam., bare near the base, distally covered with sheaths; internodes 30-40 cm long, nodal scars ca. 2 cm wide, internode surface cracking longitudinally and covered with a thick layer of dirty brown tomentum. Leaves 5-7 m long, ca. 1.5 m wide, young leaves pale green, older leaves dirty blackish green; sheath 1-2 m long, ca. 15 cm wide, markedly fibrous along margins, in mature leaves covered in dull brown tomentum, in juveniles strikingly tiger-striped with bands of pale and dark tomentum; ligule to ca. 25-60 cm long, covered in a dense layer of dirty brown tomentum, the ligule and sheath margins disintegrating into thin long black fibres; petiole ca. 1-2 m long, 2-6 x 2-3 cm in cross section, in young leaves tiger-striped with bands of pale and dark indumentum as the sheath, in older leaves dark olive green; rachis to 5 m long, to 20 x 28 mm in section in mid-leaf, adaxially with a strong flange ca. 8 x 5 mm, abaxially convex, covered in dense caduceus dark brown tomentum; primary pinnae about 20 on each side if the rachis, up to ca. 20 cm apafi, the basal primary pinnae ca. 80 cm long, the mid-leaf primary pinnae ca. 150 cm long, the distal to 100 cm long; secondary pinnae drying pale coloured, ca. 7-11 on each side of the secondary rachis, up to ca. 26 x 7 cm, irregularly wedge-shaped, leathery, veins radiating from the base, adaxially glabrous, abaxially with broad bands of caducous brown scales; transverse veinlets obscure. Inflorescences 1-2.5 m long, branching to 3 orders (always?); peduncle to 30 x 40 mm diam., the surface densely covered in dull brown tomentum; distal bracts tubular, circumscissile and leaving a low collar, splitting distally to form a triangular limb to 22 x 12 cm, edged with dark brown fibers and covered in caducous brown tomentum; basal first order branches with a conspicuous pulvinus to ca. 5 cm wide; rachillae of various lengths, the longest to at least 1 m, 3-4 mm diam., covered in dark brown indumentum; triads ca. 8-10 mm distant; rachilla bracts low, crescentic. Staminate flower at anthesis ca. L4 x 7 mm; sepals 3, dark green, strongly imbricate, irregularly gibbous, broad, rounded, entire or emarginate, the outermost 5 x 8 mm, the middle 5 x 7 mm, the innermost 5 x 7 mm, the three slightly connate basally; petals 3, free to the base, 12.0 x 4.5 mm, glabrous, smooth, almost spathulate with rounded triangular tips; stamens ca. 28, filaments 3.0 x 0.3 mm, anthers orange 5-7 x 0.6 mm, connective dark tanniniferoris, projecting beyond the anthers as a short bifid tip to 0.5 mm; pollen monosulcate, exine semitectate with anastomosed clavae forming irregular islets of tectum (Harley, pers. comm.); pistillode absent. Pistillate flower in bud (van Royen & Sleumer 6129) superficially similar to staminate flower but narrower, ca. 10.0 x 3.5 mm except at base where 6 mm wide; sepals 3, rounded, broadly imbricate, irregularly gibbous, the outer 4 x 7 mm, the middle 4 x 7 mm, the innermost 3.5 x 6.0 mm; petals 3, free in bud, 9.0 x 2.8 mm; staminodes 3 , antesepalous, filaments to 4 x 0.3 mm; gynoecium conical, 2 x 3 mm with 2 stigmas to 1.2 x 0.5 mm, ovules 2. Pistillate flower (Maturbongs MM586) post anthesin with petals basally connate for 2 mm with narrow triangular lobes to 7 x 5 mm; ovary 6 x 6 mm with 2 ovules. Fruit ripening white and then red, globose to depressed globose, to 15 x 25 mm, with apical stigmatic remains; epicarp minutely papillate. Seeds 2, hemispherical, ca. 72 x 15 x 8 mm, surface smooth, with scattered veins, with basal corky mass; endosperm homogenous; embryo lateral.
    Apart the horticultural uses, the palm is probably too rare to be of much significance.
